GAS-ENGINE.

T o all whom t may concern.'

Be it lmown that I, FRED D. Moss, a citizen of the United States, residing in the town of Seaside, county of Clatsop, and State of Oregon, have invented certain new and useful Improvements in Gas-Engines, of which the :following is a specication.

This invention relates to gas explosive engines and has for its principal object to provide an improved valve mechanism for controlling the supply of an explosive mixture to the cylinder or cylinders and the exhaust of the burned gases therefrom.

There are many diierent kinds of explosive enginesA having valve-or supply chainbers to which the explosive mixture is first supplied, with valve members, both rota-ry and reciprocating, therein,

for controlling the admission of the` explosive mixture to the cylinders of said engines, and also the exhaust of the burned gases therefrom. These valve members are of various forms, some having pass pockets of dilerent shapes and sizes therein, and some having ports therethrough, the object sought being to control in a most eilicient and effective manner the supply of an explosive mixture to the cylinder, the compression and explosion thereof, and the complete exhaustion of the burned gases from said cylinder, whereby to secure the greatest eihcicncy with as little noise and friction as possible.

Broadly stated, my invention comprises the use between the cylinder chamber and the supply chamber of an explosive engine, of two coperating valve elements, movable independently of each other, and having ports therein adapted to be moved into and out of register with each other and with the communicating port or opening between said chambers,y whereby to intermittently open communication between -the supply chamber and the cylinder chamber for supplying the explosive mixture to the cylinder, and likewise to open for exhaust purposes an outlet from said cylinder chamber. Heretofore this control has been accomplished by means Mof a movable valve member having ports therein" adapted to be moved into register with fixed ports in the wall of the valve or supply chamber.

In my invention, by supplying an independently movable port member between the movable valve member and the wall of the valve or supply chamber, I am able to Specicaton of etters Patent.

vsupply chamber with a supply of explosive mixture, or an exhaust chamber to permit the escape of the burned gases therefrom.

One practical form of the invention comprises a rotary valve meinber,`occupying.a supply or valve chamber, and having with-- in itself one or more supply or receiving chambers in communication with a source of supply of explosive mixture, with feed ports opening'therefroni, and also having within itself exhaust chambers, each open at one end and having au outlet port in its side, and a rotary sleeve or port member, with ports therein, 'interposed between said valve member and the wall of said supply chamber, said sleeve member and said rotary valve member being lrevoluble at different speeds, if turned in the same direction, to intermittently and alternately bring the ports of said receiving or supply chambers in said valve member, and of saidexhaust chambers, into register with the ports in said rotary sleeve member and saidbcylinder and exhaust tical sectional view thereof, as if taken on a line 2-2 indicated on Fig. 1; F ig. 3'- is a longitudinal sectional view through the supply or valve chamber, showing the valve member in elevation, and the intermediate port or sleeve member in section; Fig. 4 is a cross sectional view through said supplyor valve, chamber; Fig.A 5 is a. perspective view of the valve member detached, and showingl the receiving and exhaust chambers therein, with ports opening therefrom through! the wall of said valve member; and Fig. Gisa perspective view of the sleeve or port meub v ber within which the valve' member fits.

Referring now-to the''ldrawings, 1 designates a cylinder with piston 2 working therein, which said cylinder has a double wall construction to provide a water jacket 3 therefor, und which said piston 2 is connected by means of a piston rod l to a crank arm lupon a crank shaftG, mounted in the lower part of a suitable supporting casingor shell 7 for said cylinder. Mounted upon one end of said shaft l', is the usual fly wheel 8, and mounted upon said shaft at the` opposite side of said casing T are two small sprocket wheels 9 and 10, for a purpose here port member orsleeve 15, shown' in perspective view in Fig.'6, and provided with a spindle, as 16, Figs. 1 and 3, .projecting through the 'end wall of said supply chamber, to receive a driving sprocket, as 17, Fig. 1, said port' member or sleeve being open at its opposite end and provided in its sides, nextending longitudinally thereof, with two port-s, as. 18 and 19, and near its opposite .or closed end with a series of inlet ports 20+20, which-provide communication to the interiorv thereof from the supply port 13 into said supply chamber.

Rotatably mounted within said sleeve or port member 15, is avvalve member 21, shown in perspective in ig. 5, vsaid valve member having 'an operating shaft .22 extending through the spindle 16 of the sleeve 15, and the endw'all of the extension 11, to receive -a driving sprocket 23, Fig. 1, again referred to. Said valve member 21, is provided interiorly, extending ylongitudinally thereof,

with two y' oppositely disposed receiving chambers 24'-25, open at their inner ends, whereby 'to receive supplies of the explosive mixture through the openings 20-20, in the ports 26-27 'in their sides, asindicated, adapted to be alternately moved into and out of register with the port 18 in the sleeve `member 415. llt will be noted that said valve member 2l i's shorter than the sleeve mem- Aloer- 15, so that there is a space between the closed end of said sleeve and the 'inner end or saidvalve member, which is 'also closed,

1n said sleeve member.' Said valvev mem 'er zr211has also formed therein two oppositely; disposed exhaust chambers-28 and 29, open.

sleeve or port member 15, and having outletv Maase@ through the opposite end of said valve member, as ind' ated, whereby to discharge through the 'open end 11.1 of said extension l1. 30 and 31 through their sides. positioned so as to be moved into and out or' register with the ports of the sleeve member 15, as hereinafter again referred to. lt will be noted that the receiving or supply chambers 2iY sprocket chains 32 and with the sprockets 9 and 10, respectively, on the crank shaft G. The sprocket 23 is twice the diameter of the sprocketl, and four times the diameter of the sprockets 9 and 10. whereby the sleeve 15 and the valve memberl 21 are revolved.

one-half andone-fourth as many times, respectively, as is the crank shaft 6. The sleeve or port member 1 5` `will be revolved twice as fast as the valve member 21, so' that port 18 in said sleeve member will overtake the port 26 from the supply or receiving chamber 24 in the valve member, and register therewith during their movement across the opening into the cylinder chamber, whereby the downward movement of the piston 2 will operate to cause a supply of explosive mixture from the supply chamber 24 to'rush into the cylinder chamber through the ports 18 and 26, said chamber '24 being in open communication with the supply or'inlet port 13. The port- 18 in the sleeve 15 passes the port 26 in the valve lmember 21,` and thereby closes the cylinder chamber inlet. The next upy stroke of said piston operates to compress the charge of vgas confined therein, at the linishof which .the explosion takes place in the usual manner and the piston is forced downwardly on a powerstroke.

The action of the piston and crank shaft,

ywhich have traveled through one and a hah revolutions, has caused 'the 'sleeve member 15 to travel through three-'fourths of a revolution, inasmuch as said sleeve 15is geared to lthe crank shaft in the ratio ofwo to 1, and

the valve member 21, being geared in the 'rat-io of 4to' 1, revolve three-eighths of a revolution. 'llhis brings the-port 19 in the sleeve 1.5, and the lower port 30 from theexhaust chamber 28, in the valve vmember 21,

.into registerwith the cylinder opening,

whereupon'the next up s'troke'of said piston forces all the burned gases from the cylinder'.V .The continued revolutions otthe ,various- Said exhaust chambers also have ports parts again bring the port 18 in the sleeve l5, and the other supply port 27, from the supply chamber 25, in the valve member, into register with yeach other at the cylinder opening, so that as the piston starts down- Wardly, another supply of the explosive from chamber 25 is caused to move into the cylinder, as before, and thus the operation o f supplying, compressing, exploding and expelling is repeated in the operation ofi the engine.

I have shown and described but one embodiment of the invention for purposes ofl illustration, and am aware that many changes and modifications can be made therein Without departing from the spirit of the invention, and I 'do not, therefore, limit the invention to the particular form or embodiment thereof here illustrated, except as I may be limited by the hereto appended claims, forming a part thereof.
